Patch rtems-rc-4.5.0-6-cvs.diff from Ralf Corsepius <corsepiu@…>.
The patch contains:

  • build variants support
  • Reworked make-exe custom/*.cfg for all targets (Should be self-explanatory, may still be incomplete)
  • Several fixes to custom/*.cfgs related to setting debug flags
  • Fixes to some bsp_specs for BSPs which apparently have never been build with debugging before ;)
  • pc386.cfg fix attempts (cf. my mail from earlier today)
  • Updated ampolish (No need to run it, the patch contains the result from having applied it)

Known bugs/deficiencies related to this work:

  • "make [clean|distclean]" support is still incomplete (e.g. "make clean" does not delete all Depends-o-*)
  • Completely untested for linux/posix and hppa.
  • Build failures of i960 BSPs (make VARIANT=DEBUG) - I guess, they are not related to this patch.
  • Successfully tested for all sh, sparc, i386, ppc, m68k BSPs (make VARIANT=DEBUG)
  • make VARIANT=PROFILE not supported by all BSPs (I don't care :)
  • make VARIANT=DEBUG failures below tests/ for some BSPs (e.g. gensh1), because of the tests's binaries being too large to fit into the target memory layout.
  • Property mode set to 100644
